Recently, research on lightweight automobiles is increasing continuously to respond to the high safety standards and environmental regulations. The application of high strength steel is one of the effective methods for developing lightweight car bodies. A TWB (Tailor Welded Blank) is major method that allows partial high strength with light weighting using a multi-thickness and multi-material welded blank. On the other hand, additional welding process is required to prepare the blank and quality control for the welding process also required. To secure this point, the TRB (Tailor Rolled Blank) method was suggested. In the TRB method, the thickness of sheet is controlled by the rolling presses and the production efficiency is much higher than welding in TWB methods. In this study, the formability of high strength TRB steel plate was analyzed to examine the rolling effect of the blank. The formability of the specimen was tested using 0.8 and 1 mm thick steel sheets for the TRB plate. The strain was analyzed by the digital image sensing of grid markings on the specimen and the forming limit diagram was calculated. An Erichsen test for the 0.8 and 1 mm thick TRB specimens was carried out and the formability was investigated by comparing with FE analysis.

This study reviews the literature related to the omni-channel and derived structural relationship between experiential perception of omni-channel brand and consumer-brand relational quality. A total of 250 questionnaires were distributed to university students, workers, and consumers in Busan, Korea, who had experience using SSG.com. 210 questionnaires were used for final validation of research model. The hypotheses set in this study was validated through SPSS18.0 and LISREL8.3 based on the research model. The results showed that all hypotheses were accepted, except for 2 hypotheses(Hypothesis 2-3, Hypothesis 2-4). Findings of this study suggest the following:First, the consumer's experience with the omni-channel brand was found to be an important factor influencing consumers' cognitive and emotional responses formed by the transfer effect of experiential factors through senses. Second, the relationship between consumers and the omni-channel brand was found to be an important factor in building attachment and psychological bond through experience and trust for the omni-channel brand. Thus, the results of this study provide the basis for overall understanding of the strategic experiential module (SEMs) for the omni-channel, which recently emerged as a new trend of distribution channel, as well as for managing the spatial environment. Finally, we present the theoretical and practical implications related to consumers' experience and relational perception.

To increase the acceptance of multicultural youth, it is necessary to grasp the factors influencing multicultural acceptance. This study was conducted to provide basic data for a future study for the promotion of multicultural acceptance of adolescents by systematically analyzing research trends in factors affecting the multicultural acceptance of Korean adolescents. From 2008 to 2017, we searched 6,435 papers combining the keywords 'multicultural,' 'acceptability,' 'teenager,' 'middle school' and 'high school,' and analyzed six articles. The qualitative evaluation refers to Community Guide and STrengthening the Reporting of OBservational studies in Epidemiology(STROBE). The results revealed that factors influencing multicultural acceptance include gender, experience of overseas visits, life satisfaction, parental neglect and abuse, parent education, school and community factors, and community awareness. Multicultural acceptance of adolescents in Korea was influenced not only by specific factors, but also by various factors such as individual, family, school, and community. These factors were also found to change with age. Based on the results of this study, it is necessary to provide an environment and education that promote multicultural acceptance.

Power cables installed in domestic factories or underground can cause accidents depending on the manufacturing process, installation, and environmental conditions during use. When an accident occurs in a power cable, it can cause enormous economic loss and social confusion. Hence, the importance of preventive management of the cable through diagnosis is increasing to prevent it. Therefore, in this paper, a diagnostic sample cable was produced by simulating a part that could be a problem due to the installation, manufacturing defects, or deterioration of cables that can occur in the field. Dielectric loss Tangent (tan 𝛿; TD), and Partial Discharge(PD) tests were performed. Partial discharge and AC (60Hz) withstand voltage equipment using High-Frequency Current Transformer (HFCT) were applied After applying a VLF (Very Low Frequency) power supply with a frequency of 0.1Hz was applied. As a result, B and C phase defect samples at a 2.0U₀ voltage through the VLF could measure the internal partial discharge in the A-phase normal sample cable from the noise at a 0.5U₀ to 2.0U₀ voltage. In addition, the 1.5U₀ voltage was measured through the AC (60Hz) withstand voltage equipment of the commercial frequency to verify its effectiveness. Partial discharge in the run-off state was measured at a voltage of 1.0U₀, and there was a risk when installing the equipment. AC power equipment showed a difficulty of movement by volume or weight. The diagnostic method, through the VLF of the quadrant state, revealed its safety and effectiveness.

The purpose of this study is to investigate the effects of task conflict on job attitudes (organizational commitment & job satisfaction), focusing on the mediating effects of supervisory communication & co-worker communication. Recently, the importance of communication as a research topic has been increasing. According to prior research, communication satisfaction has a positive effect on job performance. However, studies which take into account the different types of communication are lacking. Therefore, this study considered two types of communication (supervisory communication and coworker communication). A research model and hypotheses were developed in order to examine the theoretical research issues and questions. The sample consisted of 280 survey data drawn from employees in firms located in Korea. The data was analyzed by the statistical packages, SPSS 21.0 & AMOS 21.0 for Windows. The findings of the analysis are as follows. Firstly, it was found that task conflict had a negative (-) effect on organizational commitment & job satisfaction. Therefore, H1a & H1b are supported. Secondly, it was found that task conflict had a negative (-) effect on supervisory communication. Therefore, H2a is supported. However, it did not have a significant effect on co-worker communication. Hence, H2b is not supported. Thirdly, as regards the mediating effect of supervisory communication, it was found that supervisory communication mediated the effect of task conflict on job attitudes (organizational commitment & job satisfaction). Therefore, H3a & H3b are supported. Finally, the mediating effect of co-worker communication was not significant. Therefore, none of the sub-hypotheses of H4 are supported. Based on these findings, this study suggested directions for future research.

Currently, green house gas(GHG) emissions in korea is aiming for a 30% reduction that it is compared to BAU by 2020. To this end, the government has proceed to a variety of reduction policies in GHG. In particular, GHG reduction effect in the public buildings is being a active discussion. It needs to reduce GHG for energy efficiency improvements in the way that public buildings are operated and maintained by public taxes. In this background, the purpose of this paper is to study environmental values judgement for non-market goods in the residents who use public buildings. The results of study are as follows; Respond to first suggested price was found the higher in price, the lower in willingness to pay(WTP). The result of second suggested price was as the same. Analysis of DBDC CVM revealed that income level shows a positive impact on WTP, but the other variables are irrelevant to WTP. Therefore, the citizen participation of the local population seems absolutely necessary to more effective GHG reduction of public sector in the future.

This study evaluated whether the installed location of air quality monitoring stations is at an optimal level in an effort to improve the health and environmental quality of the surrounding areas of the Pohang Steel Complex. As a result of analyzing the atmospheric flow field, it was found that the location of air quality monitoring stations was acceptable in case of Daesong-myeon(The 1st Division of Local Wind Sector) and Jukdo-dong(The 3rd Division of Local Wind Sector). However, the air quality monitoring stations installed at Daedo-dong and Jukdo-dong is judged to have made an overlapped measurement because the stations existed at the Division of the same Wind Sector. Accordingly, this study suggests that the further air quality monitoring stations should be additionally installed at Buk-gu areas of Pohang where more than 50% of the population of Pohang is living presently. As a result of the analysis of air contaminant concentration distribution, the Jangheung-dong area showed higher concentration distribution than other areas in case of $PM_{10}$ while the Daesong-myeon area showed a comparatively higher concentration distribution in case of $O_3$. Conclusively, this study indicates that it is high time to prepare an aggressive management of $PM_{10}$ and $O_3$ which causes a harmful impact on the life and health of the residents of the target areas.

본 연구는 고등교육기관의 평가인증제가 대학의 경영성과에 어떠한 영향을 미치는지를 알아보기 위하여 1주기 기관평가인증제가 대학 균형성과표(BSC) 4가지 관점의 성과에 미치는 영향을 검증할 목적으로 진행되었다. 이를 위하여 고등교육기관의 1주기 평가인증제에 대한 내용을 살펴보고, 대학 조직의 균형성과표(BSC) 및 1주기 기관평가인증제의 성과분석에 대한 선행연구에 대해 살펴보았다. 그리고 독립변수인 기관평가인증제 즉, 기관평가인증제도에 대한 관심의 정도, 기관평가인증의 평가준비에 대한 적절성, 기관평가인증의 자체평가에 대한 만족도가 대학 균형성과표(BSC)의 고객관점, 내부프로세스 관점, 학습과 성장 관점, 재무 관점의 4가지 성과에 미치는 영향을 분석 검증하였다. 기존의 1주기 기관평가인증제의 성과분석에 관한 선행 연구들은 주로 평가인증제 체제 자체의 성과와 각 평가요소에 있어서 대학의 변화에 초점을 두고 성과를 분석함으로써 정작 기관평가인증제가 평가인증의 평가대상인 대학의 경영성과에 미친 영향에 대한 분석은 제대로 이루어지지 못하였다. 이러한 점에서 기관평가인증제가 대학의 경영성과에 미친 영향을 분석한 결과 첫째, 기관평가인증제중 기관평가인증의 평가준비에 대한 적절성과 기관평가인증의 자체평가에 대한 만족도는 대학 BSC의 고객 성과에 정(+)의 영향을 미치지만, 기관평가인증제도에 대한 관심 정도는 고객 성과에 영향을 미치지 않는 것으로 나타났다. 둘째, 기관평가인증제 중 기관평가인증의 평가준비에 대한 적절성과 기관평가인증의 자체평가에 대한 만족도는 대학 BSC의 내부프로세스 성과에 정(+)의 영향을 미치지만, 기관평가인증제도에 대한 관심 정도는 내부프로세스 성과에 영향을 미치지 않는 것으로 나타났다. 셋째, 기관평가인증제 중 기관평가인증제도에 대한 관심 정도와 기관평가인증의 자체평가에 대한 만족도는 대학 BSC의 학습과 성장 성과에 정(+)의 영향을 미치지만, 기관평가인증의 평가준비에 대한 적절성은 학습과 성장 성과에 영향을 미치지 않는 것으로 나타났다. 넷째, 기관평가인증제 중 기관평가인증의 평가준비에 대한 적절성과 기관평가인증의 자체평가에 대한 만족도는 대학 BSC의 재무 성과에 정(+)의 영향을 미치지만, 기관평가인증제도에 대한 관심 정도는 재무 성과에 영향을 미치지 않는 것으로 나타났다. 이는 기관평가인증의 평가준비와 자체평가 과정을 통해 실질적인 교육체계 혁신이나 내부프로세스 효율성 향상으로 인해 교육의 질이 개선되어 학생의 만족도와 선호도가 높아지며, 아울러 안정적 재원확보와 재원의 효율적 관리를 가져오는 것으로 해석된다. 그리고 기관평가인증제도에 대한 인식과 관심은 인증 획득이라는 목표를 설정하게 하고, 기관평가인증의 자체평가를 통해 인증평가에서 요구하는 기준 이상을 충족하도록 학습과 혁신이 이루어지는 것으로 해석할 수 있다. 본 연구의 결과는 학령인구의 급감 등 급변하는 대학의 대내외 환경에서 생존을 넘어 지속가능한 발전을 도모하기 위해 평가인증제를 다양한 대학의 경영성과로 연계할 경영전략 수립에 유용한 정보를 제공할 것이다.
